VOICE SECURITY – HEALTHCARE
VERTICAL INSIGHTS
Healthcare faces escalating voice attacks threatening patient safety, in-room phones, clinical workflows, and sensitive data.
Vertical Profile
Healthcare depends on voice. From nurse stations and care teams to patient in-room phones and contact centers, the telephone remains the fastest and most trusted communication channel in care delivery. Unfortunately, it is also the most under-protected.
Cybercriminals exploit this reality with robocalls, spoofed numbers, vishing, and AI-generated impersonations that flood environments where every call must be answered. These attacks disrupt care, overwhelm staff, expose patients to fraud, and create dangerous openings for ransomware and data breaches.
Voice is now a frontline healthcare security issue. Protecting it is essential to patient safety, operational continuity, and meeting the growing legal standard for “reasonable” cybersecurity.
AHA Preferred Cybersecurity & Risk Provider
Mutare is an American Hospital Association Preferred Cybersecurity & Risk Provider for their Voice Traffic Filter solution.
Upcoming Events
Webinar: Enterprise Voice Security for Cisco
In this live session, attendees will explore how escalating voice threats are targeting Cisco UC, Webex Calling, and Webex Contact Center infrastructures.
WEBINAR: AI-Ready Voice Security
What was once limited to nuisance robocalls has evolved into a continuous stream of unwanted voice traffic, now amplified by automation, spoofing, and AI-driven attack campaigns.
ViVE, Feb 2026, Los Angeles, CA
Please join us in Los Angeles February 22-25 and connect with a member of the Mutare Team to discuss patient experience, patient care, and risk management.
Healthcare Case Studies
Real-World Examples of Voice-Based Risk and Defense
Case Study 158
This hospital system chose AHA-endorsed Mutare to protect its network from voice-based attacks.
Case Study 156
This healthcare system was getting overrun with spam and scam calls disrupting care delivery and threatening patients
Case Study 153
This healthcare system knew what they wanted in a call filtering solution as well as that solution provider.
Case Study 152
A large, public academic health science center was experiencing system-wide damaging impacts of spam and scam calls.
Case Study 150
Colorado hospital system chooses VTF to end the damaging, system-wide infiltration of unwanted calls.
Case Study 148
Spam calls for Indiana’s largest health care system had reached an intolerable level.
Case Study 147
In-room spam calls were impacting patient experience and CMS reimbursements.
Case Study 145
Spam calls were overwhelming nurses’ stations & patient phones.
Key Impact Zones
Key Impact Zones are defined areas of an organization where voice-based attacks cause the greatest operational disruption, human risk, and security exposure, connecting unwanted voice traffic directly to compromised services, vulnerable people, financial loss, and elevated regulatory and legal risk.
1. Patient Experience
(In-Room Phones & Patient Communications)
In-room phones are a direct line to vulnerable patients, and a growing target for fraudsters. Unprotected voice channels allow scam and impersonation calls to reach patient rooms, eroding trust, creating fear, and exposing patients to financial and emotional harm during care.
- Patient in-room phones
- Bedside communications
- Appointment, discharge, and follow-up calls
- Patient billing and financial assistance lines
2. Patient Care
(Clinical Staff & Nursing Stations)
Clinicians operate in high-stress environments where every call demands attention. Nuisance and nefarious calls interrupt workflows, distract care teams, and reduce coordination, introducing risk into settings where seconds matter and patient safety depends on focus.
- Nursing stations
- Physician and clinician phones
- Care coordination lines
- On-call and escalation paths
3. Risk Management & Security
(IT, Call Centers & Compliance)
Healthcare organizations are prime ransomware and extortion targets. Voice-based social engineering is increasingly used as the initial access vector, bypassing traditional cyber controls and exposing protected health information (PHI) and critical systems.
- IT help desks
- Contact centers and scheduling teams
- Administrative and executive lines
- Third-party and vendor impersonation
